A Video Front Collection Method of Watermarking Embedding and Blind-Extraction

摘要

In this paper, we put forward a video front collection method of watermark embedding and blind extraction. Under the premise of not affecting the video quality and the use value, this method uses the relationship of DCT coefficients to realize embedding watermark and takes the proper treatment in the corresponding position of the coefficients. We achieve the simulation which can satisfy the needs of real-time video and realize the blind extraction of the watermark. The experiment results show that it is robust against MJPEG compression.
